J solution

Well done, TBH.

Thanks, Dan. As I'm sure you recognized, the local definitions are simply for improving readability. In particular, the one for partitions (prtn) exists only to document and emphasize the partition-set that is the left argument to Interval Index. Omitting that name would still keep things simple and readable: da=. (+/\pt) I. ?y # 0

TBH I don't know if it's worth it, but another possib. for counting is: pa =. \:~ y%~ #/.~ da
